The MS5611 is a barometer and temperature sensor that communicates over I2C or SPI up to 20Mhz. Operating range: 10 to 1200 mbar, -40 to +85 °C.

Code Example

Ms5611 sensor;

public override Task Initialize()
{
    Resolver.Log.Info("Initializing...");

    sensor = new Ms5611(Device.CreateI2cBus());

    var consumer = Ms5611.CreateObserver(
        handler: result =>
        {
            Resolver.Log.Info($"Observer: Temp changed by threshold; new temp: {result.New.Temperature?.Celsius:N2}C, old: {result.Old?.Temperature?.Celsius:N2}C");
        },
        filter: result =>
        {
            //c# 8 pattern match syntax. checks for !null and assigns var.
            if (result.Old is { } old)
            {
                return (
                (result.New.Temperature.Value - old.Temperature.Value).Abs().Celsius > 0.5
                &&
                (result.New.Pressure.Value - old.Pressure.Value).Millibar > 0.5
                );
            }
            return false;
        }
    );
    sensor.Subscribe(consumer);

    sensor.Updated += (sender, result) => {

    };

    return Task.CompletedTask;

Wiring Example

To wire a Ms5611 to your Meadow board, connect the following:

Ms5611 Meadow Pin
GND GND
SCL D08 (SCL)
SDA D07 (SDA)
VCC 3V3

It should look like the following diagram:
